Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
Ethyl 6-heptyl-2-methyl-4-oxocyclohex-2-ene-1-carboxylate (CAS 304687-49-8) is a high-purity analytical reference standard with the molecular formula C17H28O3 and a molecular weight of 280.40 g/mol.
Ethyl 6-heptyl-2-methyl-4-oxocyclohex-2-ene-1-carboxylate (C17H28O3) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures Ethyl 6-heptyl-2-methyl-4-oxocyclohex-2-ene-1-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
